The 38-year-old Stuart, who is five months pregnant, was reported missing by her husband, Leslie Scott Schellenberg, who said the two of them had been playing the smartphone game "Pokemon Go", and had arrived by bus in front of Sevenoaks Shopping Centre in Abbotsford before going their separate ways.

She hasn't been seen since.

Police say they were able to corroborate Schellenberg's story by reviewing security video that showed him and his wife going in separate directions after leaving the bus.
